In the latest global cancer statistics report released in 2014, China ranked first in the world in terms of new cases and deaths from stomach cancer. China has accounted for more than 40% of new gastric cancer cases and related deaths worldwide. However, the incidence rate of gastric cancer in Japan, which is also the top of all cancers, is not a little bit better than China in terms of patient survival rate, which is a big difference. It is understood that stage I gastric cancer accounts for 50% of Japanese gastric cancer patients, and most of the stage I gastric cancer is found during gastroscopy screening, and the lesion can be removed at the same time when the lesion is found by gastroscopy. However, there are only about 5% of stage I gastric cancer patients in China, and most of them are already in the middle and late stages when they are discovered, and even a few of them have already metastasized in the distant compartment. Gastroscopy is the most effective screening method for early gastric cancer Gastroscopy has been recognized as the most effective tool for early detection of gastric cancer in the medical field. Gastroscopy is a medical examination method and also refers to the apparatus used for such examination. Gastroscopy can directly observe the real situation of the examined area, and it can further clarify the diagnosis by performing pathological biopsy and cytological examination on the suspected lesion area, which is the preferred examination method for gastric lesions. How to operate gastroscopy During stomach examination, the gastroscope is inserted into the stomach with the help of a slim and soft tube, so that the doctor can directly observe the lesions in the stomach, especially for the early detection of small lesions. As the high incidence of stomach cancer in China is well known, gastroscopy technology has been developed in a variety of ways, and major medical screening centers in the market are pushing various new gastroscopy technologies. Which technology is the most beneficial for stomach cancer screening and how do the regular cancer hospitals do it? However, it is understood that most regular hospitals do not introduce this kind of gastroscopy, which is expensive on the one hand and clinically proven for many times on the other hand, from the viewpoint of the examination effect of stomach lesions. The gastroscopy is still more reliable than conventional gastroscopy. No more fear of gastroscopy! Conventional gastroscopy is divided into traditional gastroscopy and painless electronic gastroscopy. Conventional gastroscopy is also divided into conventional gastroscopy and painless electronic gastroscopy. Conventional gastroscopy is intimidating, and many patients with gastric diseases often put off their stomach discomfort because they are afraid of gastroscopy, which leads to late detection of gastric cancer and poor treatment prognosis, and eventually leads to high mortality rate of gastric cancer in China. It is worth celebrating that the development of technology has brought a new dawn for gastric cancer patients. Based on traditional gastroscopy, our medical practitioners have explored painless electronic gastroscopy that can effectively detect gastric diseases and make the tested patient painless. The painless electronic gastroscopy is based on the traditional gastroscopy, with anesthetic drugs before the examination, so that the patient can quickly enter a state of sleep, relax and complete the gastroscopy with ease and comfort. It can greatly reduce the examination time and patient’s pain, and has a very high accuracy rate for diagnosing various stomach diseases, especially stomach cancer. Comparison between painless electronic gastroscopy and ordinary gastroscopy From the comparison, it can be seen that painless electronic gastroscopy simply wins. However, it is worth noting that although the technology is good, it is very demanding for the whole operation process. On the one hand, the amount of anesthetic drugs should be appropriate (not enough drugs will make the patient suffer, too much will have adverse effects on the patient’s body); on the other hand, the gastroscopy equipment for examination should be advanced (usually imported from abroad); especially the operating experience and emergency handling requirements of the operating physicians themselves are of paramount importance, and it is very important to choose a professional and experienced painless gastroscopy operating physician.
